For those who don't know what this means,
1. Shanks can Perform Roger's Signature Attack "Divine Departure" at Age of 15
2. He can already use Advanced CoC at Age of 15
3. Can Copy Pirate King Level Techniques without Instructions
4. Even Prime Rayleigh couldn't Copy it
This should help People realize how Insane it is for WB to talk about Legendary Duels between Shanks & Mihawk,
And also why Buggy said that Shanks was supposed to be Best of them (Forgot exact wording),
And also why Shanks is so Stressed about a Guy (Blackbeard) who managed to Scar him in his Young Days,
That Duel is also probably what gave Mihawk his Title of Greatest Swordsman,
It's also why Mihawk doesn't see anyone Stronger than Shanks
When Oda shows Real Power of Shanks, Mihawk & Blackbeard (Dragon too imo), this so-called Pirate King Level won't be fun to play with anymore.
